    It was I experimented, it is not the backfocus but the geometrical configuration of the sw reducer what denyes focus. The wo or the ts reducers are able to be inserted longer into the drawtube and also the barrel bigger than 2'' is thinner than in the sw. From my point of view it is a disaster that retailers still.offer the sw reducer for this scope having more valid options, the ts, altair astro, wo.

    Here it is, quick process of 25x300s subs taken with the QHY168C and the Optolong L-Pro filter at 30km south from Madrid downtown.

    For the record, yesterday I was not able to plate solve with APT, I did use a 332mm focal length (420 x 0.79). Today using ASPS it confirmed that the real focal length is 350mm so the TS reducer gives a x0.83 reduction when coupled with my QHY168C. Setting up in APT the 350mm the plate solving was done perfectly.

    Finally yesterday after waiting a lot, my ED72 saw first light, coupled with an Optolong L-pro filter and the TS x0.79. I did try M31 from Bortle 6-7 skies and quarter Moon. The 65mm distance from flattener to the sensor proved to be OK. I will soon post the results.

    Picture from last year (29th December), with all the problems suffered that night, bad collimatio, bad focus, astigamtism, guiding. But I think is a good example of the field given by this scope. 20 x 180 subs with the QHY168C, in this "clusters soup" in Cassiopea. M103, C10, NGC654, NGC659, Trumpler 1 and Czernik 4. Cheers. Mario.

    I also had to discard the SW reducer as I was not able to focus, due to the reducer thickness, then I went for the TS 0x79 using 65mm distance and it focus perfectly with both the IDAS and the Halpha filters. The TS has a 2'' barrel and M48 thread for filter on the tube side so it fit better. I made the measurements in another comment in this same thread.

    Simmo I did use a 33cm dovetail to proper balance the QHY168C, I also piggy back mounted the 30mm guide tube to help. Even with that is very very close to limit, see the picture

    Gents, looking for a dream scope?, see this below, OMG. https://www.teleskop-express.de/shop/product_info.php/info/p11082_TS-Optics-150mm-f-2-8-hyperbolischer-Astrograph-mit-Korrektor-und-Carbon-Tubus.html

    Well no pain no glory. But the results this thread shows with the SW130PDS have no competence at the price. For refractors you have the ED72 around 300 euros, coupled with TS optics x0.79 reducer flatenner (+ 180 eur), I have one indeed, I plan to use the 332mm focal length of the ED72 for extended nebulosity zones that the SW130 cannot cover. Meanwhile keep looking the amazing work many do with this newt bargain imager. Cheers.

    Because of the field you get with this scope if you use a 4/3 or aps sensor. Also the guiding is easy at 650mm. And it only weights 3.5kg.
  11. Susaron
    I did a bigger change, I modded the head of my AZEQ5 in order to have a dual saddle holder, so I mounted a losmandy dovetail of 33cm. Its weight assures the balancing and stiffness. Though I guide with a ZWO 30mm guidescope which is indeed lighter and all the stuff, power distribution unit and usb hub at top rear.

    Here it is, I also have a CATIA model if you need it. SW130PDSdrawing.pdf
  13. Susaron
    I have them at home, when I made the measures to Moonlite to create a plate for the SW130PDS. I will post the pdf latter. Cheers.

    I prefer the blue,

    Last Saturday the temperature stood all the session between -2º and 1º Celsius, as I was point to Auriga close to the zenith, frost started to appear over my main mirror. I have designed a support to hold a small 12V fan on the rear, fitted through the mirror cell fixed screws. I attach the .stl from Catia. I still need to send it to the 3D printer, so no final check is done. SoporteVentilador.stl

    Last picture of the year, I still can not find the reason for the astigmatism of the main mirror, and some coma I have, though the spacing is correct. IC405 Flamming Star Nebula, 37x5min subs with the QHY168C+IDAS LPS+SW130PDS+Baader MPCC+AZEQ5+ZWO 30mm guide tube + ASI385MC. Captured with APT and processed with Pix. From my point of view it still needs 2 more hours to be perfect. Cheers.
  17. Susaron
    Understood. Well this evening I am going to suffer 1 degree and 75% humidity, I will make some pictures.
  18. Susaron
    What's the reason of the rca female plug into the tube? I missed something.
  19. Susaron
    And even an azeq6, a colleague moved from a canon 550 to the asi1600mm and he inmediately noted in the elongated stars. He had to tweak phd2.

    One additional comment guys. I asked for a quotation to TS to mood the metal tube to CF, and they answer me a couple of things. First that in order to achive similar strength the thickness should be around 7mm and therefore the rings won´t be the same, and second the cost, as according to them is not a standard tube, the cost of the equivalent CF tube would be around 700 Eur. Don´t you think is this madness? Cheers.

    The long subs is the reason why I will buy the qhy, it is cooled and the pixel 3.5 promises good resolution coupled witb the sw130 or even the sw200.
  22. Susaron
    Think on the AZEQ5 as well is the one I use.
  23. Susaron
    A new objective for the big list. Anyway I am waiting for the QHY 550M to shot small galaxies and faint planetaries with the SW130PDS, but this result is tempting me.
  24. Susaron
    The secondary has a 48mm secondary axis. Anyway I have shared a season with refractor colleagues with a 100% humidity beside a river and whereas they had their dew strips at 100% power, mine one was absolutely dry with camping mat outside the tube and some flocking inside.
  25. Susaron
    M34 from last weekend very close to Madrid outskirts, I could save only 25 subs of 60s taken between the clouds. Nothing brilliant indeed but another Messier to the count.
